Umuyoboro w'icyuma wa ASTM A252 wo mu bwoko bwa 1/2/3 LSAW | OD 508-1422mm nini ifite umurambararo w'icyuma gishingiyeho Umukozi n'Umutangabuguzi

Umuyoboro w'icyuma wa ASTM A252 wo mu cyiciro cya 1/2/3 LSAW | Umuyoboro w'icyuma w'ibanze ufite uburebure bwa OD 508-1422mm

Umuyoboro w'icyuma wa ASTM A252 wo mu cyiciro cya 1/2/3 LSAW | Umuyoboro w'icyuma w'ibanze ufite umurambararo munini wa OD 508-1422mm Ishusho yagaragaye

Ibisobanuro bigufi:

Imiyoboro y'icyuma ya LSAW, ijyanye n'ibipimo ngenderwaho bya ASTM A252, ni imiyoboro y'icyuma ikomeye kandi ifite umurambararo munini ikwiriye gukoreshwa mu buhanga bw'ishingiro, kubaka ibiraro, ubwubatsi bw'amazi yo mu nyanja, n'imishinga ikomeye y'ibikorwa remezo. Imiyoboro y'icyuma ya LSAW itanga imiterere myiza y'inyubako, ubushobozi bwo gusudira neza, n'ubushobozi bwo gutwara imizigo, bigatuma ikoreshwa mu bikorwa by'urufatiro rwimbitse. Ubugari bw'inyuma buri hagati ya mm 508 na mm 1422. Iyi miyoboro y'icyuma ya LSAW ikurikije ASTM yakozwe hakurikijwe amabwiriza n'ibipimo ngenderwaho by'inganda, ituma ikomera cyane, ubugari bw'inkuta bumwe, kandi iramba cyane ndetse no mu butaka bubi n'amazi y'umunyu.

Iyi miyoboro y'icyuma ya LSAW ikwiriye ishingiro ry'ibiraro, aho kunyura ibyambu, urubuga rwo mu nyanja, ishingiro ry'inyubako ndende, n'ibikorwa remezo by'inganda. Gukorana n'abakora imirimo ya EPC benshi bafite uburambe hamwe n'ibisubizo by'inyubako mpuzamahanga bituma imara igihe kirekire, idashobora kwangirika cyane (hamwe n'amabara y'inyongera), kandi byoroshye kuyishyiraho.

Porogaramu nyamukuru

1. Kubaka Umusingi (Sisitemu y'Umusingi Wimbitse)

Ikoreshwa nk'imigozi y'ifatizo ndende ku nyubako ndende, inganda, ububiko bw'ibikoresho, amazu y'ubucuruzi, n'amazu yo guturamo. Iyi miyoboro y'ibyuma itanga ubushobozi bukomeye bwo gutwara imizigo kandi igatuma inyubako ihora ihamye mu gihe kirekire mu butaka buto cyangwa bworoshye.

2. Ubuhanga mu by'ubwubatsi bwa Bridge Foundation

Ni byiza cyane ku biraro by'imihanda minini, ibiraro bya gari ya moshi, imihanda miremire yo mu mujyi, n'inyubako zinyura hejuru y'umuhanda.Ibirundo by'ibyuma bya ASTM A252 LSAW / EFWzikoreshwa cyane mu gushingira ibiraro byo kwambuka imigezi, kwambuka ikiyaga, no kwambuka inyanja, zitanga ubushobozi bwo kurwanya imitwaro ihindagurika n'ingendo z'ubutaka.

3. Kubaka icyambu n'amazi yo mu nyanja

Bishyirwa mu byambu, mu nyubako z’amakontena, mu nyubako z’amato, ku mbuga z’ibyambu, no mu nyubako zo gupakira imizigo mu mazi. Ibi birundo by’imiyoboro y’icyuma byagenewe gushyigikira cranes ziremereye, sisitemu zo gutwara imizigo, n’ibikorwaremezo binini byo mu mazi biramba cyane mu nkombe z’inyanja.

4. Ingufu z'umuyaga zo mu mazi n'ubuhanga mu by'amazi

Ikoreshwa cyane mu rufatiro rw'imiyoboro y'umuyaga yo mu nyanja, ku mbuga zo mu nyanja, ku miyoboro y'amazi yo mu nyanja, ku nkuta z'inyanja, no mu nyubako zo kurinda inkombe.Umuyoboro w'icyuma wa LSAWIbirundo bitanga ubudahangarwa bwiza ku ngaruka z'umuraba, imbaraga z'inyanja, ndetse n'ingese zo mu mazi yo mu nyanja, bigatuma biba byiza mu bidukikije bibi byo ku nkombe z'inyanja.

5. Imishinga minini y'ubwubatsi bw'ubwubatsi

Ikoreshwa mu ngomero, sitasiyo za metro zo munsi y'ubutaka, mu mihanda, mu nyubako zirinda impanuka, no mu mishinga minini y'ibikorwa remezo bisaba inkunga y'ishingiro. Iyi miyoboro irashobora gutwara ibikoresho biremereye by'inganda n'imimerere igoye y'inyubako.

Gupakira no Gutanga

1 Paki:Imigozi y'icyuma yoroshye kuyifata. Ibyuma by'imbaho cyangwa uduce duto bishyirwa hagati y'uduce kugira ngo hirindwe ko ingingo zihinduka mu gihe cyo kuyitwara. Gutunganya ubuso (ni ngombwa): Gusiga irangi ry'umukara, amavuta yo gukumira ingese, agapira ka pulasitiki. Ibirundo bya galvanize bishyushye bishobora gutwikirwa na gapira karinda by'agateganyo kugira ngo hirindwe gushwanyagurika ku buso. Hari uburyo bwo gupfunyika bukozwe mu buryo bwihariye.

2 Gutanga:Uburebure busanzwe bw'ibicuruzwa: metero 6, metero 12. Biboneka mu burebure bwihariye. Biza na Gari ya moshi n'umuhanda. Bikwiriye gutwara abantu mu mazi, gari ya moshi cyangwa mu muhanda. Igihe cyo kubigezaho ubusanzwe ni iminsi 15-30 nyuma yo kwakira amafaranga, hakurikijwe ingano n'ibisobanuro. Bikwiriye koherezwa mu mahanga ku isi yose, hamwe n'inyandiko yuzuye (icyemezo cy'igenzura, urutonde rw'ibipakiye, inyemezabwishyu y'imizigo).

3 Amabwiriza yo kwirinda:Ntugakoreshe imigozi cyangwa udukingirizo tudafite udukingirizo kugira ngo ukore ku buso bw'umuyoboro kugira ngo wirinde ko umuyoboro wangirika. Bika ahantu hakonje, humutse kandi hafite umwuka mwiza, wirinde ingese mbere yo kuyishyiraho. Kohereza ibintu biremereye cyane kandi birengeje urugero, nyamuneka wuzuze amabwiriza yo kohereza ibintu mu gace utuyemo.

Ibibazo Bikunze Kubazwa

1. Imiyoboro y'icyuma ya ASTM A252 yo mu cyiciro cya 3 ikoreshwa?

Imiyoboro y'icyuma ya ASTM A252 Grade 3 LSAW ikoreshwa cyane cyane mu kubaka urufatiro rwimbitse mu mirimo y'ubwubatsi, nk'inyubako, ibiraro, ibyambu, inkombe n'ibindi.

2. Ni gute icyiciro cya 1, icya 2 n'icya 3 bitandukanye?

Itanga imbaraga n'ubudahangarwa bwiza cyane ku byiciro bitatu, bityo ikaba nziza cyane ku rufatiro rw'imitwaro iremereye, no ku buhanga mu by'amazi.

3. Ni ikiUmuyoboro w'icyuma wa LSAW?

Yahinduwe hakurikijwe ubumenyi bw'inzobere mu byuma, umuyoboro wa LSAW ni umuyoboro ukorwa hakoreshejwe uburyo bwo gushushanya no gusudira ibyuma mu buryo bw'igihe kirekire, ari nabyo byitwa "umuyoboro w'icyuma wometseho igihe kirekire".

4. Ni ingano n'ubunini bungana iki biboneka?

Ubunini buhari buri hagati ya mm 406 na mm 2500, naho ubugari bw'inkuta buri hagati ya mm 6 na mm 60, bukoreshwa mu mirimo yo kubaka urufatiro ruremereye n'iy'inyanja.

5. Ese ishobora gukoreshwa mu mishinga yo mu mazi no mu nyanja?

Yego. Ikunze gukoreshwa mu ngufu z'umuyaga wo mu nyanja, ku nkuta z'inyanja, ku cyambu, no ku mbuga zo mu mazi, n'ibindi. Ifite irangi ririmo epoxy, 3PE, sima yo kurwanya ingese.
